Hp50 'Integral (0,infinity,SIN(X)/X,X)' gives 5.04540304996

Yes, Radian mode set, but with degrees exactly the same wrong result, after about 23" of calculation with EMU48 on my Samsung phone.

Just for information, with HP50G:
integral of (0,100,SIN(X)/X,X)' —> 1.56222546689
integral of (0,400,SIN(X)/X,X)' —> 1.57211486927
integral of (0,10000,SIN(X)/X,X)' —> 1.57089154534
integral of (0,1000000,SIN(X)/X,X)' —>1.5762385912
and integral of (0,1000000000,SIN(X)/X,X)'
—>1.31094565782.

Besides:
Integral of (0,2*pi,SIN(X)/X,X)' —>1.41815157613
and integral of (2*pi,infinity,SIN(X)/X,X)' —> -1.91522972303;
adding those two areas: -.4970781469.
